For about the last month riding the bike within the first couple of miles the temp and gas gauges would both go all the way to the right and than after awhile go back to normal. Last night on the way home they stayed over to the right for about 15 miles before returning to normal. This morning is was ok until about riding 15 miles than they went all the way to the right and never came back to normal, even after turning the key off and back on. What am I looking for on this one? Does the y gauge work on a resistor because some gauges don't work on 12 volt they have a resistor to reduce voltages to like 7 volts. Is it maybe something like this?

Seeing as how it is both gauges giving you issues I'd bet it's your regulator failing. This is a very common problem on GL1000, GL1100, and GL1200 models. Replace the 7-volt regulator or do a search on how to check.

This is exactly how the 7 volt regulators normally fail before they die entirely. Have a look at 7 volt regulator. It has to be a regulator, because it needs exactly 7 volts for the gauges to be properly calibrated. Using just a resistor would give you anywhere from 5-10 volts depending on the speed of the engine, and the gauges would be completely unreliable.

Thanks wing Your site here is the best. I know if I have a problem can post it and you guys always comes thru. After reading your post and the part about the regulator it states its behind the gauges. Isn't it the one on the left side of the tank on the electrical panel or is there a regulator just for the gauges?

Once again THANKS guys. Rode home last night and checked it out. Pulled socket connections off and found green on them. Cleaned up and sand paper them clean, put a little dielectric grease on them and put back together. While in there did the same to all connections and rode in to work this morning and all systems are a go for now. Footnote: the ride home should put 40,000 miles on the old girl. Old Yeller doing just fine. Thanks guys
